| Abstract: | The magnetically coupled resonant wireless power transmission adopts DC chopper control over transmission power, while traditional DC chopper circuit switching has a high loss. This paper presents an improved circuit for a novel soft-switching BUCK DC-DC converter, where a coupled inductor, auxiliary inductor and diode are added to realize zero current switching-on and zero voltage switching-off. The converter has a simple structure and is easy to control. Furthermore, the paper describes the working principle and process of the circuit, designs circuit parameters, completes simulation and experimental research, and finally gives simulation and test waveforms. |
